If you were to pick a dozen likely stops on this train, you'll likely end up with a name collision. Vancouver, Washington and Vancouver, British Columbia. It's fun to think about how they would handle this. Would they use the full names in all documentation. Would they give one of the locations a nickname, such as "Southern Washington" or "British Columbia".

I also wonder what would be the largest mishap that could happen because of the name collision. Imagine going to the wrong country because of some minor miscommunication!
